The way this test generates object file results in relocation sections for .dwo sections. This is not legal. Re-wrote it to avoid those relocation sections.

For most tables, we already use commas in headers. This set of patches
unifies dumping the remaining ones.

A future MC change may add a warning/error when a .section directive
specifies incorrect sh_flags/sh_type. Fix the tests to use correct
sh_flags/sh_type.
In DWARF v5, the DWO ID is in the (split/skeleton) CU header, not an
attribute on the CU DIE.
This changes the size of those headers, so use the parsed size whenever
we have one, for simplicitly.

In DWARF v5 the Line Number Program Header is extensible, allowing values with
new content types. In this extension a content type is added,
DW_LNCT_LLVM_source, which contains the embedded source code of the file.
Add new optional attribute for !DIFile IR metadata called source which contains
source text. Use this to output the source to the DWARF line table of code
objects. Analogously extend METADATA_FILE in Bitcode and .file directive in ASM
to support optional source.
Teach llvm-dwarfdump and llvm-objdump about the new values. Update the output
format of llvm-dwarfdump to make room for the new attribute on file_names
entries, and support embedded sources for the -source option in llvm-objdump.

Emitting the correct (root of compilation) file at index 0 will be
posted for review later; I wanted to get this minor change out of the
way first.

The major visible difference here is that in line-table dumps,
directory and file names are wrapped in double-quotes; previously,
directory names got single quotes and file names were not quoted at
all.
The improvement in this patch is that when a DWARF v5 line table
header has indirect strings, in a verbose dump these will all have
their section[offset] printed as well as the name itself. This
matches the format used for dumping strings in the .debug_info
section.

This form is like DW_FORM_strp, but points to .debug_line_str instead
of .debug_str as the string section. It's intended to be used from
the line-table header, and allows string-pooling of directory and
filenames across compilation units.

The compilation directory has always been #0, but as of DWARF v5 it is
explicitly listed in the line-table section instead of implicitly
being a reference to the compile_unit DIE's DW_AT_comp_dir attribute.
This means the dumper should number the dumped array starting with 0
or 1 depending on the DWARF version of the line table.
References in the generated DWARF are correct, it's just the dumper
that was wrong. Also some assembler-coded tests were similarly
confused about directory numbers.

Update of r320852/r320886, fixing the unittest again, this time use a
raw char string for the test data.

instead of std::array to guarantee data layout.

As a side effect, the .debug_line section will be dumped in physical
order, rather than in the order that compile units refer to their
associated portions of the .debug_line section. These are probably
always the same order anyway, and no tests noticed the difference.
